The black skeletal dial of this men's watch from the maquina automatic collection by bulova elegantly displays the inner workings of the automatic movement in action. A sapphire crystal tops the 46mm yellow-gold-tone stainless steel case that includes a crown at 2 o'clock, and a deployment buckle secures the yellow-gold-tone stainless steel bracelet. The men's watch is water-resistant to 30 meters.
